The French tactician, who recently became the Gunners' longest-serving boss, turns 60 on Thursday.
However, he is not thinking of retiring and believes he can stay in football in some capacity for a long time to come.
"If I have health, I want to work as long as I live but adapt to my potential," said Wenger.
"It doesn't always need to be physical work, it can be more intellectual. You cannot be 75 on the pitch - although Trapattoni has done well and he is 70.
"I don't know how long I will manage the team. From now on I have to assess every two years because this job is hands-on."
The only way Wenger wants to celebrate his landmark birthday is with victories over AZ Alkmaar and West Ham this week.
Wenger took charge of Arsenal in 1996 but he has lost none of his enthusiasm for the job and feels the current crop of players can be successful.
